高能时多个部分子的相互作用重要吗?新型强子产生过程

Are multiple parton interactions important at high energies? New types of hadrons production processes

V. A. Abramovsky

摘要:

高能强子的相互作用是通过单色胶子交换进行的。碰撞强子中包含的所有夸克和胶子都参与了相互作用和粒子的产生。多个部分子相互作用的贡献可以忽略不计。高能多重强子的产生只发生在三种过程中。第一个过程是胶子弦中的强子产生,第二个过程是双夸克弦中的强子产生,第三个过程是三夸克弦中的强子产生。在质子-质子相互作用中,只可能产生胶子弦和两个夸克弦。在质子-反质子相互作用中,胶子弦的产生可能是双夸克弦和三夸克弦。因此,质子-质子和质子-反质子相互作用的多重数分布是不同的。

英文摘要:

Hadrons interaction at high energies is carried out by one color gluon exchange. All quarks and gluons contained in colliding hadrons take part in interaction and production of particles. The contribution of multiple parton interactions is negligible. Multiple hadrons production at high energies occurs only in three types of processes. The first process is hadrons production in gluon string, the second is hadrons production in two quark strings and the third is hadrons production in three quark strings. In proton-proton interaction production of only gluon string and two quark strings is possible. In proton-antiproton interaction production of gluon string, two quark strings and three quark strings is possible. Therefore multiplicity distributions in proton-proton and proton-antiproton interactions are different.
